> In AttemptFailedTransition, the new attempt will get
> state('justFinishedContainers' and 'finishedContainersSentToAM') reference
> from the failed attempt. Then the two attempts might operate on these two
> variables concurrently, e.g. they might update 'justFinishedContainers'
> concurrently when they are both handling CONTAINER_FINISHED event.
